Abstract

A vehicle having (i) a rotatable platform for securing a load thereto, and (ii) an object detection system for detecting an object in the vehicle'"'"'s path of travel. The sensitivity of the object detection system is variable so that it can be varied based on the rotated position of the load.

Claims

1. A vehicle comprising:

a drive frame, said drive frame being capable of propelling said vehicle in response to at least one drive control signal;

a load platform operatively coupled with said drive frame for carrying a load, wherein said load platform is capable of being rotated in relation to said drive frame;

a controller, said controller operatively coupled to said drive frame and being capable of generating said at least one drive control signal;

an object detector, said object detector being operatively coupled to said controller, wherein said object detector communicates with said controller when said object detector senses an object within a predetermined distance of said vehicle; and

a swivel disposed between said load platform to said drive frame.

2. The vehicle of claim 1 wherein said predetermined distance is adjustable.

3. The vehicle of claim 1 wherein said predetermined distance is automatically adjusted based on a rotated position of said swivel.

4. The vehicle of claim 1 further comprising a rotation sensor operatively coupled to said load platform, said rotation sensor being capable of determining a rotated position of said load platform.

5. The vehicle of claim 4 wherein said rotation sensor communicates with said controller to permit said controller to cause said swivel to rotate said load platform in relation to said drive frame.

6. The vehicle of claim 4 wherein said predetermined distance is automatically adjusted based on said rotated position.

7. The vehicle of claim 1 wherein said swivel is a ball bearing swivel.

8. The vehicle of claim 1 wherein said load platform has at least one rotation memory position.

9. The vehicle of claim 1 further comprising a rotation locking mechanism operatively coupled to said load platform, wherein said rotation locking mechanism inhibits rotation of said load platform when engaged.

10. The vehicle of claim 1 wherein said load platform includes frame mounts to restrict movement of said load with respect to the load platform.

11. The vehicle of claim 1 wherein said drive frame includes a drive wheel and a rigid castor.

12. The vehicle of claim 1 wherein said object detection system further comprises at least one distance sensor, said distance sensor being capable of determining a distance from said object detection system to said load, whereby said predetermined distance is automatically adjusted based on said distance.

13. The vehicle of claim 1 wherein said controller communicates with a remote controller to cause said swivel to rotate said load platform in relation to said drive frame.

14. The vehicle of claim 1 wherein said swivel is driven by an electric motor.

15. The vehicle of claim 9 wherein said controller communicates with said rotation locking mechanism.

16. The vehicle of claim 1 wherein said controller communicates with said object detector and a rotated position of said swivel to determine a bank length.

17. The vehicle of claim 16 further comprising a rotation sensor operatively coupled to said load platform, said rotation sensor being capable of determining said rotated position.
